Underhanded Tactics

Prerequisites, Have a Charisma and a Dexterity of 14+

Throu;ghout the years of performing and decieving you've found a way to integrate it into the battlefield. For an Action you can pretend to have gone prone after trying to attack a creature within 10 feet of you, You'll roll a Charisma check, while the creature you've targeted rolls an insight check. If the creature fails the insight check it will try to harm you while prone but you catch it off gaurd and make a melee attack that will be rolled as if it was a critical roll. If the creature succeeds the creature will have an oppurtunity attack. Regardless of Success or Fail, every use of this ability after the first use in combat any creature you use this feat on will have advantage on insight. This Feat is not effected by abilities that allow you to use an action more than once, i.e Action Surge, Extra Attack, Etc.
